# Active Directory Connector Overview

Active Directory Connector (ADC) provides a method for replicating a Microsoft Exchange Server version 5.5 directory with the Microsoft Windows 2000 Server Active Directory. You can perform replication from either direction, depending on how you configure the connection agreement.

Use ADC to:

- Replicate selected containers in the Windows 2000 Active Directory to equivalent containers in the Exchange Server directory.
- Replicate selected Exchange directory containers into equivalent Windows 2000 Server Active Directory containers.

## Microsoft Windows 2000 Server Active Directory Users and Computers

The Windows Administrator manages users, groups, and contacts within the Windows 2000 Server Active Directory. When you perform directory replication from Windows to Exchange, the selected Windows 2000 Server Active Directory objects are added to the Exchange directory.

## Microsoft Exchange Server Administrator Program

The Exchange Administrator program manages mailboxes, custom recipients, and distribution lists within the Exchange directory. When you perform directory replication from Exchange to Windows, the selected Exchange objects are added to the Windows 2000 Server Active Directory.
